I don't want to de-laminate the fog light that doesn't have a problem.

If my dealership was sketchy and dishonest, I'd be more likely to take this kind of advice. But my dealership is known to have very high customer satisfaction, so I'm not worried about it. They wouldn't have earned this reputation by pulling stunts like telling a customer that his fog light has moisture on the inside because the lens has a laminate on the outside.
